HERMAN L. GREVE, OF HOLLIS, NEW YORK, ASSIGNOR INTERNATIONAL MAILINGTUBE AND WRAPPER COMPANY, OF BROOKLYN, NEW YORK, A CORPORATION OF NEWYORK CARTON FOR SHIPPING PURPOSES Application filed February 16, 1929.Serial No. 340,616.

My invention relates to cartons for shipping dress goods, etc. v

The object of my invention is to provide a carton of strong fibre-boardformed to pre- 3 sent an overlapping interlocking joint cover portionwhich serves to stifien the cover, and prevents moisture and dust fromentering the interior of the carton thru the joint.

A further object of my invention is to pro- M vide a pilferproof cartonwhich cannot be opened without detection.

The further objects and advantages gained by the present constructionare hereinafter set forth.

Referring to the drawings which form a part of this specification:

Fig. 1 is a plan view of the blank as it is formed ready for folding.

Fig. 2 is a plan view of a carton in its open 29 condition, and arrangedto be closed with its end flap portions of the cover resting on theoutside ends of the carton, as illustrated in Figure 5. r

Fig. 3 is an end view of the carton as it appears when staples are usedto hold the end portions together as shown, and showing the constructionwherein short tab portions are provided, and which fold upwardly overthe ends of the cover portions to permit the locking means to be locatedon the top side of the carton, as illustrated in Figure 4.

Fig. l is an end view of the construction shown in Figure 3, after it isclosed and locked.

Fig. 5 is an end view of the construction as illustrated in Figure 2,.after it is closed and locked.

When made for shipping dress goods, such as a dozen silk dresses, or anovercoat, these cartons are made 26 inches long, 16 inches wide and 3 or4: inches in depth, and therefore the fibre-board is made very thick andstiff to resist crushing and to carry the contents safely to theirdestination.

The blank is scored on the dotted lines A shown in Figure 1, and thelines B indicate slits which extend from the edge of the blank to thescored lines A. The portions between the dotted lines or scored areasindicate the bottom portion 0-, the side portions C CAD and cover,portions D having flap interlock ing portions D and D 'respectively, theportion D' being made of greater width than that of thep-ortion D Theblank is notched as shown at E- to provide endportions D of the cover,and end portions F- which extend outside ofthe portions G, and arepreferably connected thereto by staples H but may be cemented togetherif desired. 1 7 When the gcartonis constructed'to be locked at the topend as shown in Figure 4, the blank is slitted at.II respectively, toprovide end tabs J'J respectively, which extend'upwardh ly from thebottom of the carton over the end portions'D- of the cover portions, andare locked by snap-locks-K' to the top of the cover portion asillustrated. The snaplocks used are well known and used'to per manentlyfasten theflaps in locked engage- I0 ment, or to the top of a carton,and are broken in order to open the carton, and therefore, if thejointsand other overlapping portions of the carton are protected sothat theycannot be separated, and the cartonis locked or sealed so that no partof the contents can he removed from the carton without breaking thelock, or the carton, pilfering will be practically impossible withoutthe detection of. the fact that the carton has'been tampered with.

When the carton is to befoldedas shown in the constructionillustrated inFigures 2 and 5, Iprefer to form the blank without the slitslf, and inthis easel attach the snaploeks to the bottom ofthe carton and to theouter edge of the end cover flaps D- as shown, to lock the cover portionto the bottom of the carton. I

As before stated, the card-board material is very heavy and stiff, andhard to bend, and therefore I have found it necessary to score the innerinterlocking flap member D?- at D-* with one or more longitudinallyextending score lines, which prevents the spring-like action of theinner flap D pressing the edge of the flap upwardly under theoverlyingfiap portion D- and causing it to bulge upwardly due to theresiliency I of the bent portion M. "i

When the carton is closed, the portion is folded under the portion D toform an interlocking joint which extends the entire length of thecarton, and provides 5 four thicknesses of material which strengthensthe entire carton longitudinally and also provides a joint whicheffectually prevents anything from being removed from the carton thrusaid joint portion, and which also 19 stiffens and strengthens the endport-ions of the carton.

The interlocking construction of the joint may be made of greater orless width than that shown in the drawings, it being understood that Iprefer that the width of the said portions shall be substantially thesame, the outer flap being necessarily somewhat greater in width thanthe inner portion.

In making the cartons as shown in Figures 29 1, 3 and 4, I prefer toform semicircular notches L- in the ends of the interlocking flapportions, to permit the two parts forming the lock K- to be drawn closertogether in the locking operation, since the 2 material will yield abovethe notches a little and thus permit this to he done.

It will be noted that the entire carton is made from a single blank of aform in which a minimum of waste material is provided,

30 which reduces the cost of the carton, and

permits the blanks to be shipped in knockdown form to customers.

Having thus described my invention I claim as new:

A carton formed from a single sheet of fibrous material of substantiallyelongated rectangular form, scored lengthwise and laterally to define acentral bottom portion with narrowed transverse walls adjacent A0thereto and narrowed end walls, cover forming portions having end flapsfolded on lines longitudinally of the sheet, narrow flap portions at theouter edges of the cover forming interfolding portions for the cover,the said end walls being slitted to provide flaps between the sides ofthe bottom portion with the outer free ends of the flaps adapted forattachment to the cover portions.

In testimony whereof I have affixed my signature.

HERMAN L. GREVE.
